抚顺西露天矿西区改变采矿工程推进方向的研究

Research on changing mining engineering advance direction in west area of Fushun west open-pit mine

抚顺西露天矿煤炭和油母页岩富矿2种有益矿物经过百年开采,尤其是近2年南帮边坡变形回填压脚和北帮局部滑坡压埋采区,所剩资源可采储量严重不足,已进入收尾期。针对目前采矿技术面貌现状,本着科学合理、切实可行的原则,对西露天矿区采矿方法进行了大胆研究,鉴于西区采场空间狭小,提出改变西区采矿工程推荐方向,由原来东西拉沟降深,南北推进,变为南北拉沟降深,从东向西推进,并对采空区及时回填压脚实现横采内排,快采快填。

Through 100 years mining in Fushun west open-pit mine, mining reserves of coal and oil shale rich ore have a serious shortage especially in south slope deformation backfill and the local landslide buried mining area of north slope. According to the present situation of mining technology feature, the article researches the mining method in west open-pit mine and presents changing mining engineering advance direction in west area which is from the original east west slotting drawdown and south north advance to south north slotting drawdown and east west advance and makes goaf backfill to realize transverse mining internal dump and quick mining quick filling.
